I am making a character map but I need a symbol for each important character that I can put by the name. I am thinking of putting masks or crown or something like that.
for example, Bayardo San Roman might have a crown because he is very rich.
The twins might have executioners hoods because they kill Santiago Nassar.

So for those that have read it, what to you think some good ones to use for the main characters?
For those who haven't read the book, what are some good masks/hats/headgear-type things that I could use for a character? just throw some suggestions out there.
